Gather three flat pie plates or wide shallow bowls.
For the breading
In the first, stir together the flour, cayenne, salt, and garlic.
In the second, beat the eggs and stir in the yellow mustard until combined.
In the third, lightly toss the panko and parmesan until mixed.
To slice the eggplant
Thickly slice the eggplant into 5 slices. Then slice each slice into 8 "fries". You'll end up with approximately 40 fries.
Roll a few "fries" into the flour first, then using a fork, coat completely with the egg/mustard. Finally, roll it in the panko/parm until covered.
In a single layer, place the breaded eggplant in the air fryer basket. "Fry" at 400° for 11-15 minutes according to your air fryer instructions. Check the eggplant at the 8 minute mark and then again around 12 minutes, flipping as needed.
Mix the sauce ingredients together and serve on the side for dipping.
Don't have an air fryer?Bake at 400˚ on a sheet pan lined with a rack for approximately 20 minutes until crispy. Flip halfway through to bake evenly.Serving, Storing, & Reheating
Eggplant fries can be breaded and refrigerated earlier in the same day before frying.
Can be frozen in a single layer on a baking sheet and transferred to a freezer bag for up to 3 months.
Reheat in an air fryer for about 3-5 minutes or a 400˚ oven for 5 minutes.
